Overview of topic
Pulmonary cycle or respiratory cycle involves two steps-breathing in or inspiration and breathing out or expiration. During inspiration organisms inhale oxygen and during expiration organisms exhale the carbon dioxide.
Inspiration takes place when the lungs pressure is less than the atmospheric pressure. The diaphragm goes down to increase the volume of the thoracic cavity. Intercoastal muscles pull sternum and ribs upward, all the movement of the diaphragm, ribs and sternum result in the increase in volume of thoracic cavity. The increase in volume of the cavity causes lesser pressure than atmospheric pressure. Air goes from higher pressure (atmosphere) to lower pressure (lungs).
Expiration takes place when the lungs pressure is more than the atmospheric pressure. The diaphragms go to theri position.Intercoastal muscles pull sternum and ribs downwards, all the movement of the diaphragm, ribs and sternum result in the decrease in volume of thoracic cavity. The decrease in volume of the cavity causes higher pressure in lungs than pressure in atmospher. Air goes from higher pressure (lungs) to lower pressure (atmosphere).
